Baotou City, The Composition Of Wireless Digital Tv Network And Application

This article describes the City of the principles of wireless digital TV network implementation, system architecture and application status, elaborated on SDH digital microwave transmission, digital television platform, digital MMDS building approach and the specific composition of the various parts.

Introduction Baotou City is a large industrial city in north China, with a total area of 27,768 square kilometers, population 2.4 million, under the jurisdiction of the nine counties in the district, of which five agricultural counties in the district, more than 70 million population, rural and pastoral areas an area of 26,499 square kilometers, a vast terrain. Both in the vast grassland, there are rolling mountains; both the relative concentration of the population living in rural areas, there are few of pastoral staff. As the geographical distribution of population and economic conditions and other factors, construction through the city’s rural and pastoral areas Cable television There are enormous difficulties in the network. In recent years the construction of “villages” project, mostly small pieces of cable network and, Number of Programs few poor signal quality, but due to maintenance management system and maintenance funding reasons, many a “back to blind” phenomenon. Even the nine urban areas around the original area, with many farmers and herdsmen can only open the way to receive 3-4 sets do not know the wireless analog TV signals. How to farmers and herdsmen from the fundamental solution to the difficult problem watching TV, construction of rural and pastoral areas Radio and TV Basic network to ensure network security and long-term nature, so that the peasants and herdsmen to see dozens of sets of high definition Digital TV Program is the development of Baotou City, and radio and television building of new socialist countryside is an important topic.

2004 onwards, according to national SARFT Digital transformation of microwave proposed policy guidelines, Baotou City, Radio and Television Bureau of the original three analog microwave circuits the digital transformation; and a new digital TV platform and five digital MMDS, transfer of 56 sets of digital television programs.

Initially built the city’s wireless digital TV backbone network, the basic construction of the rural, pastoral radio and television public service system, and achieved good social and economic benefits.

Wireless digital TV network role and function

Baotou wireless digital TV network construction and operation, full account of the header of economic strength, geographical location, population distribution and existing resources, access to different ways to expand digital radio and television and agricultural science and technology information of Wireless Coverage . Wireless digital TV network has the following features:

(1) ethnic minority border areas to promote the development of radio and television to meet the farmers and herdsmen of the spiritual and cultural needs, improve the cultural quality of farmers and herdsmen and rural morality to Baotou rural and pastoral areas before entering radio and television the digital age.

Further narrowing the urban-rural information gap, opening up the rural and pastoral areas and popularizing science and technology skills training the new channel.

(2) further strengthened the security of the city’s radio and television broadcast and security systems, give full play to the national security alert system, improve the prevention of hostile forces radio and television signal interference and destruction of infrastructure capacity.

(3) according to the state of the microwave, Satellite , Cable, three different transmission techniques in the planning, construction strict compliance with its network of national and industry standards, optimizing resource allocation, to ensure that the wireless digital TV network management, maintenance, operations security, stability and reliability.

(4) wireless digital TV network construction, the completion of the microwave transmission equipment, digital transformation, so that microwave transmission of this important strategy, combat readiness, resources and technical support means and its effects into full play. And, for the first time in SDH digital microwave transmission circuits 3 mountain microwave relay station, microwave-frequency repeater technology with success. Save a lot of construction and maintenance funds. More than 5000 km for the Inner Mongolia Autonomous Region in Digital Transformation accumulated experience.

Wireless digital TV network access basic programs

According to the actual situation of Baotou City, the whole city wireless digital TV network construction is in accordance with the different regions, different users, by SDH microwave transmission system and digital MMDS cover system, flexible digital television programs and information cable network in all counties in the area rural pastoral cable network and scattered small pieces of the user’s wireless access of farmers and herdsmen.
